How much debt does MPLX have?

Can you provide me with a detailed breakdown of MPLX's current debt situation? I'm particularly interested in knowing their total debt amount, the composition of their debt portfolio in terms of short-term versus long-term debt, and any significant changes in their debt levels over the past few years. Additionally, I'd like to understand if MPLX has any plans to address their debt burden in the NEAR future, such as through debt refinancing or other debt reduction strategies.
